Laser Not Fully Cutting Through Material

I am currently now having issues with the laser having to run 2 passes in order to cut material i put in the glowforge even with proofgrade material and settings used. I was wondering has anyone else experience this and are there any solutions to this instead of running 2 passes which I hadn’t have to do originally.

I am cutting basic things like puzzles on draft board and the board is completely flat.

Usually when this happens to me, that means my Glowforge needs a cleaning.

If you are still having issues after a cleaning, then it might be something else.

Thanks @joe, that’s right! @designer, if that doesn’t do it, please continue with the instructions in our troubleshooter and let us know how it goes.
